Apparently, Sprint is ending its pursuit of T-Mobile US. Sprint and its parent, SoftBank, decided it would be too difficult to win approval from regulators.

Sprint is also expected to replace its chief executive, Dan Hesse.

Sprint's decision didn't have anything to do with the surprise bid for T-Mobile by France's Iliad. Rather, the US regulatory hurdles were the key.

Here are four cold, hard realities of Facebook's privacy policies -- and what you can do about them right now:

1. You can't stop receiving ads on Facebook -- but you can keep Facebook from aiming specific ad topics at you.
2. As long as your browser keeps cookies, you can't stop Facebook from tracking you according to age, gender and where you live. But you can stop it and other companies from using that information to deliver ads.
3. You can stop Facebook from knowing your phone's location and limit it from using other information to target ads.
4. Unfortunately, all of these rules could change later.

The wireless industry is an aggressive marketing category and has spent $1.77 billion on national TV advertising through the first half of the year, much of it on broadcast television, according to data from research firm iSpot.

While wireless industry’s top two commercial advertising spenders -- AT&T T and Verizon -- spent similar amounts on broadcast television spots through the end of June, they allocated that spending among networks differently. AT&T, the wireless brand that has spent the most on TV commercials so far in 2014, has spent $480.2 million on TV ad placements through June 30, according to iSpot.

Meanwhile, Verizon has spent $408.5 million on TV ad placements through June 30, concentrating its commercial spending on Fox, NBC and ABC.

France’s Iliad which runs mobile carrier Free Mobile, has been operating in the French mobile market since early 2012, and had taken a 12% share of the market by last December.

Its launch sparked a price war in France, with the company offering cut-price plans for as little as €2 ($2.68) a month. The company’s founder is a price cutter at heart–a good match for T-Mobile’s current approach to shaking up the U.S. market.

The French government asked the country's antitrust authority to study whether Iliad, France's new cut-rate mobile-phone operator, is benefiting from a sweetheart roaming agreement, potentially giving ammunition to incumbent companies that have argued the deal is forcing them to cut jobs.

France's independent competition watchdog said that it will give an opinion by the end of February on whether Iliad's Free Mobile, France's fourth mobile-phone operator, would gain a "lasting advantage" over competitors if it extends its roaming agreement with partly state-owned France Télécom SA, the country's largest mobile-phone operator by subscribers.

The government also asked the authority to weigh in on whether France's mobile operators can pool resources to roll out shared wireless networks in rural areas, as well as whether the operators can share wireless networks in urban areas "without harming competition, jobs and investment."

There is a new frontier in cybersecurity: The computers masquerading as phones in consumers' pockets. Smartphones are constantly connected to the Internet, infrequently updated and are challenging to secure. They're rich targets, recording pictures, names of associates and conversations.

French upstart telecommunications company Iliad has made an offer for T-Mobile US in a bold bid to counter by Sprint for the fourth-largest wireless carrier in the US. Iliad announced that it offered $15 billion in cash for 56.6% of T-Mobile US at $33 a share.

Iliad said its offer for T-Mobile US, which is majority-owned by Deutsche Telekom AG, "should not raise any antitrust issue in light of the competition rules given that Iliad is not present in the United States."

Cable magnate John Malone says 21st Century Fox has long been eyeing a takeover bid for Time Warner and isn't likely to face competing bidders, pouring cold water on speculation that tech companies could emerge as rival suitors for the TV and movie company.

"It's such a large magnitude transaction," Malone said, adding that Fox's ability to pay with nonvoting stock and to access cheap debt means "that it would be very difficult to put together a competitive bid."

After less than a decade of existence, smartphones and tablets in 2014 will draw more money from advertisers than the centuries-old newspaper industry or the nearly century-old radio sector, a sign of just how rapidly technology is transforming media habits.

But given how much time Americans spend on their devices, mobile-ad spending could be much higher, an indication that marketers remain uncertain about the medium's effectiveness. Research firm eMarketer estimates that spending on mobile advertising, which includes both smartphones and tablets, will soar 83% to nearly $18 billion in 2014. Newspapers will draw nearly $17 billion, while radio will bring in $15.5 billion.

Still, the imbalance remains stark: American adults now spend almost a quarter of their media time on mobile devices, eMarketer estimates, yet 2014 spending growth will raise mobile's share of the ad market to only 9.8%. By contrast, American adults spend only 2% of their media time reading newspapers but ad spending for the sector hangs just under 10% of the overall market, eMarketer estimates.

European Union antitrust regulators are preparing to step up their investigations into Google on several fronts, including revisiting a proposed settlement over its search-engine practices that has met with unprecedented opposition.

The European Commission is likely to revise some terms of a settlement announced in February, aimed at dealing with concerns that the company abuses its dominance of online searches in Europe, a person with knowledge of the situation said.

The antitrust probes are only one element of a number of challenges faced by Google in Europe, where the company has faced allegations over issues ranging from corporate taxes to copyright issues to data privacy.

The commission is also deepening a second line of investigation into Google's business practices relating to its Android operating system for mobile phones. The Android inquiry isn't yet a formal investigation, but it is likely to become one, the person said.
